Often specifically about JLCPCB and KiCAD. If a crystal says 20pF, it probably actually wants caps of 35pF each. C = 2L-5pF, or so. Then pick an available capacitor near that value. JLCPCB's understanding of 45* rotated components is 90* off of KiCAD's, in some way. ...But only on the pcb bottom? Expect also disagreements … Continue reading General PCBA notes
